保存iphone

當我在iphone模擬器中輸入一個值並按下保存按鈕它只保留值，直到模擬器運行的值的問題。當我重新啓動模擬器並按下加載按鈕時，它會顯示me.i.e輸入的較早值，但它不能保留新值並只保留舊值。保存iphone

我正在使用以下循環來保存文件和加載文件。

-(IBAction) save{ 

    NSUserDefaults *sinner=[NSUserDefaults standardUserDefaults]; 

    [sinner setObject:serverIP.text forKey:@"load"]; 


    NSUserDefaults *king=[NSUserDefaults standardUserDefaults]; 

    [king setObject:noc.text forKey:@"save"]; 

    } 


-(IBAction) load { 

    NSUserDefaults *sinner=[NSUserDefaults standardUserDefaults]; 

    NSString *tempstring =[sinner stringForKey:@"load"]; 


     serverIP.text = [NSString stringWithFormat:tempstring]; 



    NSUserDefaults *king=[NSUserDefaults standardUserDefaults]; 

    NSString *tempstring1 =[king stringForKey:@"save"]; 


    noc.text = [NSString stringWithFormat:tempstring1]; 




    }

// Your code  
NSUserDefaults *king= [NSUserDefaults standardUserDefaults]; 
[king setObject:bookmarks forKey:@"Bookmarks"];  
// saving it all 
[king synchronize];

-(IBAction) save{ 
NSUserDefaults *sinner=[NSUserDefaults standardUserDefaults]; 
[sinner setObject:serverIP.text forKey:@"load"]; 
[sinner setObject:noc.text forKey:@"save"]; 
[sinner synchronize]; 
}

這應該保存的內容。你不需要兩個單獨的userdefaults。加載它們，你可以嘗試

-(IBAction) load { 
NSUserDefaults *sinner=[NSUserDefaults standardUserDefaults]; 
NSString *tempstring =[sinner stringForKey:@"load"]; 
serverIP.text = tempstring; 
NSString *tempstring1 =[sinner stringForKey:@"save"]; 
noc.text = tempstring1; 
}

希望這有助於
